BP5250/BP5250-24 The BP5250/BP5250-24 are DC/DC converters for step-down that can drive PchFET using PWM system. The voltage setting resistor and the combination of external power elements enable you to make any power circuit to your liking. High-efficient DC/DC converter can be made easy by adding external components such as I/O smoothing capacitor without designing circuit. Applications OA appliances(copy machine,personal computer, facsimile), AV appliances (car navigation, DVD etc.), and industrial appliances. Features 1) High power conversion(η=90% Vin=12V 5V/2A) 2) Power save pin(Leakage current at OFF mode : IR=10μAMAX) 3) Output voltage can be established from 1.5V to 9V in the VADJ pin.(For BP5250, however, output voltage is limted by input voltage.) 4) With recovery type overcurrent protection function (Detection current can be established by the external current detection resistance.) 5) Power circuit can be made easy by adding external smoothing capacitor and power element. 6) Reference voltage accuracy 1.25V±1% Absolute maximum ratings (Ta=25°C) Recommended operating conditions (Ta=25°C) DC/DC converter ParameterSymbol Limits Unit Input voltage ESD endurance Operating temperature range Storage temperature range Allowable max surface temperature The power saving terminal voltage Vi Vsurge Topr Tstg Tfmax V CTL BP5250 24 24 1 −40 ∼ +85 −50 ∼ +100 100 BP5250-24 30 30 V kV °C °C °C V Condition DC (EIAJ ED4701-1C-111A) Ambient temperature+The module self-heating ≤ Tfmax Vi ≥ VCTL ParameterSymbolUnitMax.Typ.Min.
